SWITCH-STAN D lSIGNAL'.

SPECIFICATION forming part of LettersPatent No. 402,328, dated April 30, 1889.

Application filed February 29, 1888. Serial No. 265,992. (No model.)

To all whom t may concern:

Be it known that I, MICHAEL I3. HURLY, of Quebec, Canada, have invented a new and useful Improvement in Switch-Stand Signals, of which the following is a specification.

My invention is an improvement in switchstand signals intended especially for use with three'- way switches, or switches by which trains may be directed from aY main line or track tol lines or tracks on opposite sides thereof.

l The invention consists in certain features of construction and novel combinations of parts, as will be -hereinafter more fully described and claimed.

In the drawings, Figure l is a perspective view of my improved device. Fig. 2 is a front View thereof. Fig. 3 is a detail vertical section on about Yline a; cc, Fig. 4c; and Fig. 4 is a cross-section on about line fy y, Fig. 3.

I have not thought it necessary to show the switch in my drawings, as the details of construction thereof form no part of the present invention.

The switch-stand A may be of any suitable form orconstruction. Alongside of this stand I Vjournal the operating-shaft B, having near its lower end a crank, b, to which I secure the switch rod C, by reciprocating which the switch-section may be adjusted into line with the main track or either of the side tracks, as desired, and as will be readily understood.

The target D and hand or pointer E are secured on the upper end of the operating-shaft, and are turned by said shaft into alignment with the main track or to point toward the side track that is registered with the movable switch-section. Near its upper end the operating-shaft has a vcrank-arm, F, for the purposes presently described.

On the switch-stand I mount an upright -shaft or rod, G, which may be secured to the switch-stand by threading the lower end of the rod G, passing such end through an opening in the platform of the switch-stand, and securing it bynuts above andbelow such plat-A form. On the rod G, I iiX the lamp H, which lamp is held from turning and maybe of any suitable construction. Over this lamp I lit an opaque hood, I, which, like lamp H, is held from turning, and is provided with two diametrically opposite light-openings, through `will be understood from the drawings.

which the light of the lamp may be emitted. Over the lamp and hood I it the lanternJ, which has six light-openings', arranged in pairs, the openings of each pair being diametrically opposite each other and covered with the same-colored glass, the glass over each pair of openings being different from that over the other pairs.

Manifestly the colors employed may be of any suitable character decided on by the railroad authorities in any given instance. This lantern is suitably supported over and detached from the hood and lamp, so it can be revolved independently thereof. To this end I prefer to provide the lantern with a depending tube-like portion, K', which encircles and may turn on the rod or 'shaft G, such tube K being provided with a crank-arm, L, connected by a link, M, with the crank-arm F on the main shaft, so that the turning of the latter will Leffect a turning of the lantern to correspond with the turning of the hand or pointer, as The lantern being secured on the rotating sleeve and made to revolve on the stationary lamp and hood, corresponding colored lights'will only be seen through in the desired direction A up and down the railway-track. The lantern not having to move as far on its center as the target and pointer in order that the desired colored light may be properly adjusted to correspond with the direction indicated by the adjustment of the pointer-hand, the crankarm F may be made shorter than the crankarm L, the cranks F L being connected, as described, so that when the rails are switched to either right or left of main line a changed and distinct colored light will only be seen up and down the track, indicating to the engineer by color of light, as also by the indicating-hand on the target, the direction intended for the locomotive.

Manifestly the target may be of any desired form, and the indicating hand or pointer may be constructed to appear either within the margin of or outside the target, but so placed as to point in the direction of the set switch.

In order that the light from the lamp may be cast on the colored glass of the lantern with the best effect, I provide within the opaque hood reflectors R, which reflect the light through the opposite openings of the hood onto the colored glass, as will be understood from the drawings.

Suppose in practice that a railroad company should select for signal-colors for this purpose white. For left throw of switch the shield would be thrown across the main line and the indicating-liand would be pointing to the left. The locomotive-driver (engineer) would then see a white light, not in direction of the hand, but up or down the track, as the case may be, so that if he wanted to go on the left track and did not see a white light he would know that the switch was not properly set for him; but should he see a green light instead he would know that the switch was set for the right throw. If he saw a red light ahead, he would know that his course was on the main or center line. You can see from this that the indication-liglit is always seen to turn on the center of the track, the indicating-hand pointing directly onto the intended changed direction. The only time the target and hand point in the saine direction as the light is when the red light would be shown. Then the target is turned edge on to main line and the hand points directly down to the center or main line.

Having thus described my invention, what I claim as new is- 1. In a switch-stand signal, the combination of a fixed signaling-lamp, an opaque hood iitted thereover and having light-openings in two opposite sides, and the lantern fitted over said lamp and hood and detached therefrom, such lantern being provided with liglit-opeiiings and suitably supported, whereby it may be revolved to bring any two of its light-openings into register with those of the opaque hood, all substantially as and for the purposes specified.

2. The combination of the switch-stand, the operating-shaft, a pointer on said shaft, a lamp fixed on said stand, a lantern fitted ovei` said lamp and having light-openings and suitably supported, whereby it may be revolved, crankarms connected with said lantern and with the operating-shaft, and a link connecting such cranks, whereby the turning of the shaft will effect a turning of the lantern, substantially as described, and for the purposes specified.

3. The improvement in switch-stand signals, substantially as herein described and shown, consisting of the operating-shaft, the upright shaft or rod mounted on the switch-stand and having the lamp fixed on its upper end, the opaque hood having opposite light-openings and fitted over the lamp, the lantern having light-openings and fitted over the hood and lamp and havin g a depending sleeve encircling the upright rod and provided with a crankarm, a crank-arni on the operating-shaft, and a link connecting such arms, substantially as set forth 4. In a switch-stand signal, the combination of a fixed signal-lamp, an opaque hood fitted over said lamp, and the lantern fitted over said lamp and hood and suitably supported, where by it may be moved rotarily, substantially as set forth.

5. In a switch-stand signal, the combination, with a fixed lamp, of an opaque hood fitted over said lamp, and having a refiector or refiectors, R, and a lantern fitted over the lamp and hood and adapted to revolve, substantially as set forth.
